Your immediate problem here is that your  element has an id, but no
name attribute. That is why you are getting None when you try to retrieve
it from the POST dictionary -- the browser never sent it to the server.

I'm certain that you have additional issues with your view function, but
this is the reason for the error that you are seeing right now.

Why are you running django-admin.py, rather than manage.py? manage.py knows
how to fund your settings files, and import all of your apps and check all
of your template dirs.

Try first running "manage.py makemessages -l fr" (since I suspect that your
site is already in French, you won't have to actually do anything with that
po file right now, but it's good to have)

\d+ ensures you will only get naturals, but django will not perform any 
conversion automatically. Especially not here as it would require introspecting 
the regular expression to see which pattern was matched and whether it is 
convertible.

models.TimeField returning string rather than datetime.time with MySQL backend

2012-02-26 Thread smcoll 
i need to interact with an existing MySQL database table, so i built a
models.py file in a new app via introspection and then cleaned it up a
bit.  For the TIME types, i am using models.TimeField, which maps to a
TIME type when using the MySQL backend.

Here's a sample from that models.py file:

http://dpaste.com/hold/708356/

What's strange is that when i'm accessing that `time_of_day` field,
it's returning as a string rather than a datetime.time:

>>> from reporting.models import FooModel
>>> m = FooModel.objects.latest()
>>> m.time_of_day
'09:19:00'

To be sure of the expected behavior, i set up a mock project with a
corresponding MySQL database on the same server.  models.py:

http://dpaste.com/hold/708357/

Now, when i grab that `time` field, i get a datetime.time, which is
the expected behavior (note the final line):

>>> from timetest.models import Widget
>>> w = Widget.objects.latest()
>>> w.now
datetime.datetime(2012, 2, 25, 18, 45, 8)
>>> w.datetime
datetime.datetime(2012, 1, 1, 1, 23, 45)
>>> w.date
datetime.date(2012, 2, 2)
>>> w.time
datetime.time(12, 34, 56)

i haven't been able to explain the difference in behavior.  The only
differences between the two databases and their respective tables that
i can think of are:
 - the introspected database and tables weren't created by the Django
ORM
 - the introspected tables are InnoDB and the Django-generated tables
are MyISAM
 - introspected table row format are "compact" and Django-generated
row format are "fixed"

Using 1.3.X. Any idea what's going on?

I figured out the error.

At the end of the method we were returning 0 and 1 that will throw the error.

Is there some rule in django that we are not supposed to return integers?

>From the looks of it, you might benefit if the m2m relation would be
hand-defined, and activities then relate to that model. Something
like:

class Trip:
...
class Destination:
...

class TripDestination:
trip = models.ForeignKey(Trip, related_name='destination')
destination = models.ForeignKey(Destination)
class Meta:
unique_together = ('trip', 'destination')

class Activity:
at = models.ForeignKey(TripDestination, related_name='activities')

Now, the correct way to display all this data is to do (pseudo-code):
{% for trip_dest in trip.destinations %}
   {{ trip_dest.destination }}
   {% for act in trip_dest.activities %}
 {{ act }}
   ...

Be careful, the above generates a lot of queries. You would benefit a
lot by using 1.4 beta and its prefetch_related feature. In 1.3 you can
do the prefetching by hand in your view code by something similar to
what you do currently. However I usually assign the prefetched list
directly to the related model. Something like:

trips = list(Trip.objects.all())
# Make sure every trip has a list of destinations
[setattr(trip, 'trip_dest_lst', []) for trip in trips]
# This will allow fast joining, we can find the trip by its PK fast...
trip_dict = dict([(trip.pk, trip) for trip in trips])
trip_dests =
TripDestination.objects.filter(trip__in=trips).select_related('destination')
 # Here we append the trip destinations fetched above to related
trip's trip_dest_lst
[trip_dict[td.trip_id]trip_dest_lst.append(td) for td in trip_dests]

Now every trip should have (possibly empty) list of trip destinations.
You will still need to do the same for the activities per trip
destination, exactly same logic applies. Note that the above is not
tested, it is almost guaranteed to not work correctly.

In the template you would of course use the trip.trip_dest_list
instead of trip.destinations.all().

internationalization makemessage don't work

2012-02-26 Thread nicolas HERSOG 
Hi folks !

I'm trying for hours to internationalize my django website.

I added to my settings.py this few lines :

TIME_ZONE = 'Europe/Paris'
LANGUAGE_CODE = 'fr-FR'

I added to all templates i want to translate the tag trans for the sentence
I want to  internationalize exemple :

{% trans "article écrit :"%}
{% trans "Nom :"%}

And then at my root project i run django-admin.py makemessages -l en

This command created a django.po file which contains the translations key
for django debug tool bar, but none key of my webapp.

Did I do something wrong, or miss something ?

Thank you :)

Nicolas

Hi,
You could also pass a variable in the response's dictionary and use
javascript to check this variable and navigate appropriately. This
variable should indicate if postback or new request.

Question on unknown error

2012-02-26 Thread Stanwin Siow 
Hello,

I have the following method:

def subscribe_keyword(userid,subDay =7,KEYWORD_SET=frozenset()):
try:
...

sub_datetime = datetime.datetime.now()
exp_datetime = sub_datetime + timedelta(days=subDay)
print 'time'

However when i try to run my app,

The following error throws at those two lines.

Err: sequence item 0: expected string, int found
Is there something wrong with the module?





Best Regards,

Stanwin Siow

Presuming you mean a specific row rather than a specific column, you use 
one of the queryset filtering or slicing options.

eg to get the Keyword whose name field is 'foo':
Keyword.objects.get(name='foo')

or to get all the Keywords whose name field starts with 'bar'
Keyword.objects.filter(name__startswith='bar')

or to get the first Keyword in the database:
Keyword.objects.all()[0]

etc.
As always, all this is explained in the tutorial and fully documented in 
the query method reference.

Re: Using query set in views.py

2012-02-26 Thread Stanwin Siow 
Ok disregard my previous question.

Here's the latest one.


I have the following form in my HTML:

Keyword: 





when the user presses the submit button, it will go to the method 
keyword_subscribe in views.py


The method is as shown:

def keyword_subscribe(request):
if request.POST:
username = UserProfile.objects.all()
#userid = username.objects.all()
subscription_days = "7"
new_keyword = request.POST.get('myTextField')
print new_keyword
new_keyword_subscribed = 
subscribe_keyword(username,subscription_days,new_keyword)

response = simplejson.dumps({'new_keyword': new_keyword_subscribed})
   
print new_keyword_subscribed  
else:
   # html = form.errors.as_ul()
response = simplejson.dumps({'success':'False'})
return HttpResponseRedirect("/accounts/login/")
#if request.is_ajax():
 #   return HttpResponse(response, mimetype='application/json')
#else:
 #   return HttpResponseRedirect("/")

Once in this method, i'm supposed to extract the word which the user entered in 
the textfield and store it in a variable called new_keyword

However, i've been getting NONE which means there's something wrong somewhere 
and i do hope someone can help me.

In addition, i would like to get the username which is stored in the 
UserProfile table in my database to be passed as a parameter to the next 
function too.

How then do i implement the queryset needed?

This should be clearer. 

Thank you.


Best Regards,

Stanwin Siow

Raspberry Pi Live

2012-02-26 Thread Addy Yeow 
Hey folks,

Just sharing a Django-powered page to get live status off raspberrypi.org:
http://dazzlepod.com/raspberrypi/

Raspberry Pi is an ARM GNU/Linux box for $25 (model A) / $35 (model B).
It is expected to be available for order in the next couple of days
but the first batch will only see release of 10,000 units.

Anyone looking forward to create first Django-powered site off the Raspi?

Cheers,
Addy

Re: Using query set in views.py

2012-02-26 Thread Stanwin Siow 
Sorry if i have misled anyone.

Here's a better view on what i'm asking.

def get_keyword():
   return Keyword.objects.all() 

That method above returns me a list of Keyword items correct?

How then do i get a specific item from that list?

Keyword is a table in my database but i need a specific column's information in 
my views.py.

Hope that makes it clearer.

Using query set in views.py

2012-02-26 Thread Stanwin Siow 
Hello,

I was wondering if we are able to use querysets in views.py so i can use one of 
the columns in my method below:


def keyword_subscribe(request):
keyword= ''
if request.method == 'POST':
subscription_days = "7"
new_keyword = request.POST.get('myTextField')
new_keyword_subscribed = subscribe_keyword(username,subDay 
=7,KEYWORD_SET=frozenset())

response = simplejson.dumps({'new_keyword': new_keyword_subscribed})
  
else:
html = form.errors.as_ul()
response = simplejson.dumps({'success':'False', 'html':html})
if request.is_ajax():
return HttpResponse(response, mimetype='application/json')
else:
return HttpResponseRedirect("/")
